Now that the H616 (and variants) audio codec is supported, enable it for boards with a mainline DTS. The Tanix TX1, Transpeed 8K618-T and X-96 Mate have all been tested with the onboard 3.5mm audio jack and the Orange Pi Zero 3 with a 3.5mm jack connected to the audio header. The RG35XX (2024, -H, -Plus and -SP variants) are also tested working but have a separate mux and GPIO-controlled (PI5) power amplifier to support both a headphone jack and onboard speakers. The headphone jack has a GPIO for jack detection, but this is not currently supported by the driver, so audio is heard both via the headphone jack and speakers when the speaker amp is powered (by the CLDO1 regulator, defined as always-on until proper jack detection is implemented). Define the audio codec and routing for all supported H616 and variant boards, and power and speaker amp enablement where present on boards and known.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
